6.1 SINGLE IMAGE MODE
Use this mode to acquire single images or sequences; for the
alternative
Double Image
mode, see chapter
6.2
.
The functional principle of the single image mode is explained on the
basis of the following timing diagram.
Timing Diagram
Exposure Trigger
In most practical applications an external exposure start trigger signal
will be used as shown above. The triggering event is always the rising
edge of the trigger pulse.
The camera works strictly sequentially; the next trigger signal is only
accepted if the readout of the last image is completed; see trigger
pulses marked as not accepted.
Image Intensifier
The image intensifier and the sCMOS sensor can be considered
separately. For the proper operation of the intensified camera system
both components are internally synchronized at highest precision.
The settings in pco.camware for exposure / delay time apply directly
to the image intensifier itself and the sCMOS sensor follows
automatically.
There are fixed parameters (intrinsic delay, phosphor decay) and
selectable parameters (delay time, exposure time).
The four stages of the intensifier exposure process are listed:
•
Fixed Intrinsic (system) Delay (about 50 ns, see pco.final test
sheet for precise value of your camera)
• User selectable Delay time
